SPATIAL DESCRIPTION OF HEART CHAMBERS DEPENDING ON CENTRAL HEMODYNAMICS TYPES

The objective was to study the peculiarities of spatial structure of healthy heart chambers in different types of central hemodynamics. The hearts of practically healthy albino male rats have been examined which were divided into groups in according to the three types of cardiac hemodynamics. The dynamics of changes of planimetric and volumetric parameters of the heart chambers of healthy rats with different types of central hemodynamics has been studied. The endocardial surface square of the right chambers was found to be bigger than the same parameter of the left chambers(1.2 times in all the experimental groups). Volume characteristics of the left ventricle were smaller than those of the right ventricle (reserve volume of right ventricle was twice as the same indices of the left ventricle). Spatial characteristics dominated among the animals with hyperkinetic hemodynamics type.
